However, right now the form is "signing" with Canvas, and I was thinking of a solution using digital certificate and electronic signature, to take it when I export the PDF (I use jsPDF for it).
I'm not very focused on this and I do not know if it would be viable. What can you tell me?
I was currently looking at libsodium (Paragonie), but I do not know if I'm worth it for this purpose.
Do you know if it is generally possible and what would be needed?
